Currently the patch only changes break to use goto statement instead.
But not necessary acutually since the ret value checked after the for loop.
So it is okay for the break case before changed by the patch also.

This patch only reverts the following commit partially.
  https://github.com/openwrt/openwrt/commit/ddc11c3932c7b7b7df7d5fbd48f207e7
    Note: The changes are mainly applied into the linux kernel upstream.
